What a beautiful plant! As far as I can tell this is Phoradendron leucarpum, the false mistletoe native to North America. The berries are ripening right now (mid February).
The berries remind me of bubble tea tapioca pearls. You can -almost- see through them.
Here’s a picture of the evergreen leaves:
I took this photo to show how it grows from the host tree:
Now that the last of the deciduous leaves have fallen the mistletoe bunches are easy to spot. I had always thought they liked oak trees and evergreens but the ones I saw were growing on deciduous trees such as hackberries!
I happen to have a hackberry. Who doesn’t? Extra bonus: false mistletoe is a host plant for the Purple Hairstreak butterfly.
